ELECTRIC SWITCH.

SPECIFICATION forming part Of Letters Patent N0. 635,691, dated October24, 1899.

Application filed February 24, 1899. Serial No. 706,674. (No model.)

To ctZZ whom it may concern.-

Be it known that 1, CHARLES J. KLEIN, a citizen of the UnitedStates,'residing in the city of New York, borough of Manhattan, countyand State of New York, have invented certain new andusefullmprovementsin Electric Switches, of which the followingis a specification.

My invention relates to electric switches adapted to effect a rapidclosure or break of the electric circuit.

Iwill describe electric switches embodying my invention and then pointout and claim the novel features of my invention.

In the accompanying drawings I have illustrated several forms of switch,each embodying the central idea of my invention, although I do not wishto confine myself to switches shown, as the details may be variedwithout departing from the spirit of my invention.

In the drawings, Figure 1 is a plan View of a hand-snap switch embodyingmyinvention. Fig. 2 is a side view thereof. Fig. 3 is a plan View of asingle push-button switch embodying my invention, Fig. 4: being asectional side elevation thereof on line 4 4 of Fig. 3. Fig. 5 is asectional side elevation of a double push-button snap-switch embodyingmy invention. Fig. 6 is a bottom view of the switch shown in Fig. 5.Fig. 7 is a top view thereof. Fig. 8 is a sectional side elevationshowing the contacts, and Fig. 9 is adetail of the shoe.

In the drawings similar letters of reference refer to similar parts inall the figures.

Referring for the present to Figs. 1 and 2, a is a porcelaininsulation-base for the support of the contacts. I) are the contacts. 0is the supporting frame or bar, having a bearing face or surface 0. d isa rocking lever, shown in the present instance as pivoted at d andprovided with a bearing face or surface d The switching piece or bar 6is preferably carried upon the end of a cross-bar f and preferablyinsulated therefrom. One of these switching-pieces is carried at eachend of the cross-bar, although but a single piece can be so carried, ifdesired. Carried upon the cross-bar f is a shoe g, which carries theswitching piece or pieces 6 and slides upon the bearing-face c of theupright or supporting-frame c. h is a grooved roller which bears uponthe bearing-face d of the rocking lever 01 and is provided with an axlei, to which a spring or springs j are seen red, which spring or springsconnect the roller-axle 7, with the cross-bar f.

The operation of the switch will be apparent from the drawings. Uponrocking the lever (1, let us say in the direction of the arrow, thebearing-surface (1 becomes inclined with respect to the bearing-surface0, so that the tension of the spring or springs being exerted to pullthe shoe and roller toward each other the said shoe and roller will besnapped downward, causing the contact-piece e to close the circuitbetween the contacts or springs Z) I). The parts will then be in theposition shown in dotted lines. When it is desired to open the switch,the lever 01 is rocked in the opposite direction, thereby increasing thetension on the springsj and inclining the upper end of thebearing-surface d toward the bearing-surface c, whereupon the shoe androller will rise, breaking the circuit.

It will be apparent that the underlying principle of my invention may bevariously applied, and I have shown by way of example the principleapplied to other forms of switches.

In Figs. 3 and 4 a single push-button is employed. In these figu res, kis a spring-restored push-button, which operates upon a rocking lever01, acting upon a guide or supporting frame a in proximity tocontact-springs b.

The supporting-frame c carries a sliding shoe or contact-piece g, whichis connected by a spring j, whose end or moving piece moves on therocking lever d.

In Figs. 5, 6, 7, and 8 a shoe 9 slides upon a supporting-frame c andcarries a shaft f, provided with contacts e, placed in operativeproximity to circuit-terminals or contact-- springs b. Pivot-ed to theframe a is a rocking lever 0, provided with a bearing-surface and stops01 This rocking lever is operated by a pair of push-buttons 7t 7t and isprovided with a roller 71, connected to the shoe g by means of springsj. The switches shown in Figs. 3, 4, 5, 6, and 7 operate in a similarmanner to the switch shown in Figs. 1 and 2. The shaft f is insulatedfrom the contactblocks 6 by insulation Z. The shoe has a projection Zentering between the side bars of the supporting-frame c, as clearlyseen in.

ing the circuit between the terminals com-' prising a plurality ofbearing-surfaces one capable of being inclined with respect to theother, a plurality of moving pieces each freely moving or sliding upon abearing-surface and a spring connection between the moving pieceswhereby an electric circuit may be opened or closed by inclining one ofthe bearing-surfaces with respect to the other, substantially asdescribed and for the purposes set forth.

2. In a switch of the character described, the combination withcircuit-terminals, of means for closing the circuit between theterminals comprising a fixed bearing-surface, a movable bearingsurfacaaplurality of springconnected pieces one bearing upon each of thebearing-surfaces whereby when the movable bearing-surface is inclinedwith respect to the other bearing-surface a movement of opening orclosing the switch is effected.

In an electric switch, the combination with circuit-terminals, of meansfor closing the circuit between the terminals comprising the supportingframe or bar 0, the rocking lever cl and a plurality of moving piecesone moving freely upon the supporting frame or bar and the other movingfreely upon the rocking lever, and a spring connection between the twomoving pieces, whereby upon movement of the rocking lever the springconnection will be effective to open or close the switch. t.

4. In an electric switch, the combination with circuit-terminals, ofmeans for closing the circuit between the terminals comprising asupporting-frame and rocking lever provided with bearing-surfacescapable of being made substantially parallel with or being inclined withrespect to each other and a plurality of freely-moving pieces onecooperating with one bearing-surface and the other with the otherbearing-surface and a spring connection connecting the said two movingpieces whereby when the bearing-surfaces are substantially parallel witheach other the movable pieces will receive no motion and when thebearing-surfaces are inclined with respect to each other the movingpieces will be forced CHARLES J.
